The “Exosuit,” a next-generation atmospheric diving system capable of taking a diver down 1,000 feet at surface pressure, will be on temporary display at the American Museum of Natural History from February 27 to March 5 in the Irma and Paul Milstein Family Hall of Ocean Life.

A team of researchers led by scientists from the American Museum of Natural History has released the first report of widespread biofluorescence in the tree of life of fishes, identifying more than 180 species that glow in a wide range of colors and patterns.
